It is a vertiginous thing to have so much freedom—to be always self-skeptical, always testing the reasons for your beliefs, always prepared to abandon them for something better. If you can do anything you want, then every day becomes an existential problem—an empty space of possibility that has no ceiling but also no walls and no floor.
To think continuously about changing the world is to spend your life looking at what is bad in it. To be attached to the world is to be attached to the world as it is, and not for any reason, because reasons can always be countered. To consider the world from first principles, to think about how well it would work if everything were different, is to be ready to throw away everything you know. Radical idealism and a sense of limitless possibility are the brighter facets of absolute rejection.
